Frozen Bubble [www.frozen-bubble.org]
It's open source, and it's as addictive as I remember Tetris being when it first came out. It's actually a very similar concept - kind of like tetris upside down with discs that have gravity fields.
RedHat users will find pain free installation RPM files at this site: http://oandrieu.nerim.net/frozen-bubble/
The main site downloads page includes versions for Windows and MacOS X, but I haven't tried them yet...

frozen bubble on Windows
I just tested a windows installer of froze bubble, and it worked perfectly. You can download it from your nearest sourceforge mirror at: http://prdownloads.sourceforge.net/fbe-win32/fbinstaller.exe?download
